- PROBABILITY FUNCTIONS
-
-
- This program enables you to compute a variety of probability statistics
- or related functions. All input is from the keyboard so no data file is
- needed.
-
- You will be presented with a menu from which you can select the desired
- function by pressing the lower case letter beside the option which you
- wish to use.
-
- All output is sent to the screen. However, you can use the "PrtSc" pro-
- cedure to obtain a hard copy if desired.

-
- INPUT AN INTEGER VALUE
-
- If you will enter an integer value its factorial will be computed and
- reported to you. If you enter a negative value, it will be converted to
- a positive integer.
-
- If you wish to exit you may enter an * and press <cr>.

-
- PERMUTATIONS AND COMBINATIONS
-
- Enter the value of n and press <cr>. Then enter the value of r and press
- <cr>. The number of permutations and combinations will be computed for
- n things taken r at a time.
-

-
- T- AND Z-RATIO PROBABILITIES
-
- If you have a t- or z-statistic, enter the number of degrees of freedom.
- The one- and two-tailed probability will then be computed and reported.
-
- If you wish to exit you may enter an * and press <cr>.

-
- F-RATIO PROBABILITIES
-
- Enter dfn = degrees of freedom for the numerator and press <cr>. Then
- enter dfd = degrees of freedom for the denominator and press <cr>. Enter
- next the value of the F-statistic and press <cr>. The probability for
- the upper tail of the F-distribution will then be reported to you.
-
- If you wish to exit you may enter an * and press <cr>.

-
- BINOMIAL PROBABILITIES
-
- Enter n = an interger and press <cr>. Enter r = an integer less than n
- and press <cr>. Then enter p = the probability for of a successful outcome
- ( 0.0 >= p <= 1.0 ). The results reported are the probability at x = r and
- the cumulative probability for x >= r.
-
- If you wish to exit you may enter an * and press <cr>.

-
- POISSON PROBABILITIES
-
- Enter m = the mean and press <cr>. Enter x = a value in the distribution.
- The results reported are the probability of obtaining x and the probability
- of obtaining a value of x or greater.
-
- If you wish to exit you may enter an * and press <cr>.

-
- GEOMETRIC PROBABILITY
-
- Enter n = the number of trials until the first success is observed (must
- be an interger) then press <cr>. Enter p = the probability of a successful
- outcome ( 0.0 >= p <= 1.0 ). The results reported are the probability at
- x = n and the cumulative probability from x to n.
-
- If you wish to exit you may enter an * and press <cr>.

- 09
-
- HYPERGEOMETRIC PROBABILITIES
-
- Enter N = the total number of elements, press <cr>. Enter r = the total
- number of successes in the N elements, press <cr>. Enter n = the number
- of elements drawn from N, press <cr>. Enter x = the number of successes
- that were drawn from n then press <cr>. The results reported are the prob-
- ability at x and the cumulative probability for x through n.
-
- If you wish to exit you may enter an * and press <cr>.

-
- EXPONENTIAL PROBABILITY
-
- Enter the mean and x = the point at which you wish the probability to be
- computed at. Note that the results for a continous random variable is
- reported in terms of area. The area beyond x and the area below x are
- reported.
-
- If you wish to exit you may enter an * and press <cr>.

-
- CHI-SQUARE PROBABILITY
-
- Enter the degrees of freedom, df, and press <cr>. Then enter the value
- of Chi-square and press <cr>. The reported probability is area in the
- upper tail of the Chi-square distribution.
-
- If you wish to exit you may enter an * and press <cr>.
